So the prices of gas will be quite a bit higher in September and October?
Yes, or at least they will be unless something else manages to put a lid on the price of refined gas (and usually the only thing would be a crash in demand, which would only be likely if something rather ugly is happening elsewhere in the global economy). The current crude prices should become fully reflected in the price at the pump sometime around the last couple weeks of September or so, maybe the first week of October.
This simply could not come at a worse time. People who pay little attention to politics til election time will see gas prices above 2.00 in October and will hear Kerry say something about prices being too high and how he will fix that problem and they will say time to vote for a change...sigh...remember, most foreign leaders want a wimp for prez and are probably doing what they can to push the prices up...
